Abstract:
This bachelor`s degree thesis is based on analysis, modeling and control for a resonant LLC converter that already exist, in fact it’s for the hardware TMDSHVRESLLCKIT by Texas Instruments. First, a description of the behavior of the resonant converters are made, the next step it’s to modelling the converter using the first harmonic method (FHA). Normally, the converters are used to regulate the output voltage, so design a closed-loop controller it’s necessary to achieve it. Then this closed loop design would be proved experimentally to verify it and for have a complete study of the kit supplied by Texas. Finally, a double-loop controller is proposed as an alternative for the single-loop voltage controller.
